Pipercross performance air filter - Morgan 4/4 and Plus 4

Performance filtration specialist Pipercross may be best known for its vast range of competition, tuner and sports car filters, but the firm also has a wide range of classic and retro car applications, too – including the superb Morgan 4/4 and Plus 4 in both 1.6 and 2.0 guises.

Like the cars themselves, all Pipercross filters are entirely hand-finished here in the UK, making them the ideal upgrade for any cherished Morgan. Different fitments are available to cater for the ’68-82 1.6, the later ’82-85 inlet design for the same displacement and the 2.0i engine that ran from ’88 to ’92. As each filter solution leaves the entire factory air box untouched, it’s also an insurance and originality-friendly improvement that enhances that character and performance of the car, without spoiling it.

All Morgans boast reasonably respectable performance figures from the factory, but really respond well to breathing modifications, with a panel filter and exhaust upgrade often being the first improvements that many owners make. The Pipercross filter is designed to be an exact replacement for the rather asthmatic factory paper filter and uses multiple foam layers to allow up to 30% more air-flow through to the engine, improving power, torque and drivability over the stock set-up.

As well as increased flow rate, thanks to its unique multi-laminated open cell polyurethane foam construction, the Pipercross upgrade can actually filter down to a much finer rate than the OEM part, preventing any foreign particles from entering the induction tract, meaning even greater protection for the Morgan’s engine. This same construction means that the filter can also go longer between service intervals than even leading cotton-gauze filters, before needing to be cleaned.

Best of all, despite these impressive abilities, the Pipercross filter comes with a lifetime warranty and can be easily cleaned again and again for re-use, providing decades of faithful service and paying for itself many times over.

The price for any of the three filters is £29.99 +VAT (£35.99 inc.) Bearing in mind that it’s the only one you’ll ever need - what are you waiting for?
